Project description:We recently identified the nonreceptor tyrosine kinase syk as a tumor suppressor in pancreatic ductal adenocarcinoma cells. Reintroduction of syk into Panc1 cells promoted a more differentiated phenotype and retarded invasion and tumorigenic growth. Gene array analysis identified over 2,000 transcripts differentially expressed at FDR<0.01. Among these were members of the MMP2 axis, which were subsequently shown to regulate Panc1 invasion. Experiment Overall Design: Affymetrix global gene arrays were used to analyse differences in gene expression patterns in Panc1 cells stably reexpressing syk, or vector-only mock controls. RNA was harvested from cells grown under identical conditions in standard culture.
Project description:We report expression profiles for mouse testes carrying a Phf13 knockout in comparison to wildtype testes. Upregulation of X- and Y-linked genes is evident after loss of PHF13.
Project description:The effects of mutant p53 on TNFa stimulated PANC1 cells was tested. PANC1 cell harbor endogenous mutation in p53 (R273H). We knocked down this mutp53 (using sirna for p53) and then treated with low doses of TNFa to detect any differential transcription regulation governed by mutp53. A total of 7 samples, 3 of them were duplicated

Project description:We investigated the role of PHF13 in TGFβ-induced Epithelial-to-Mesenchymal Transition and found PHF13 is essential for TGFβ-promoted broadest H3K4me3 domains and super-enhancers activation.

Project description:Panc1 (human pancreatic adenocarcinoma cells) cells were transfected with control siRNA (targeting firefly luciferase, siLuc) or siRNA targeting GLI1 (siGLI1, Pool of four siRNAs). 72h following transfection, RNA was prepared for array analysis.
